Air pressure threads?

[schaney]

Frog, to the best of my knowledge this isn't available online. I get copies of the pages I need from the wholesaler I purchase my tires and wheels from. Any tire stores should have a copy or access to it.

Yes, your tires are only one piece of the puzzle for your load capacity.

Hugh, what your describing tests how flat your tire thread is riding, which impacts even tire wear. In no case such you go below the minimum tire pressure for how much your rig or trailer weighs loaded for on road usage, especially at highway speed. Lightweight vehicles with big C or D rated tires on them, with rims on the narrow side, Samurai's with 33" tires on 8" rims, can be hard to get them to ride flat in a safe air pressure range.
